Panel for Measurement of Power in Three Phase Circuit by Three Wattmeter Method

The Panel for Measurement of Power in Three Phase Circuit by Three Wattmeter Method trainer from Glass Agencies is a laboratory training system developed to demonstrate the measurement of active power in three-phase circuits using the three-wattmeter method. This setup allows learners to gain practical experience in analyzing both balanced and unbalanced three-phase loads, studying line and phase currents, voltages, and the distribution of power across all three phases. The system converts theoretical knowledge into observable results, helping students understand the principles of three-phase power measurement and the application of multiple wattmeters for accurate readings. The trainer is mounted on a sturdy and well-finished base panel to ensure stability and secure handling during repeated laboratory experiments. It includes three-phase supply terminals, three wattmeters, ammeters, voltmeters, control switches, protective devices, and clearly labeled terminals for organized and systematic wiring. Insulated wiring and an orderly layout support safe experimentation and convenient operation. Learners can perform experiments by connecting various three-phase loads, recording readings from all three wattmeters, and calculating total active power, load distribution, and power factor. The setup allows observation of the effects of balanced and unbalanced loads, phase sequence, and load variations on power measurement, providing a comprehensive understanding of practical electrical systems. Accurate instruments and robust construction ensure reliable readings and repeatable results, which are essential for academic evaluation, performance analysis, and reporting. The structured layout simplifies wiring, improves component visibility, and allows convenient connection of auxiliary measuring devices or external loads. This makes the trainer suitable for engineering colleges, polytechnic institutes, and technical training centers where three-phase power measurement, electrical machines, and instrumentation form part of the curriculum. By translating theoretical concepts into practical experimentation, the system strengthens understanding of the three-wattmeter method, power distribution, and phase relationship analysis. Its compact design allows placement on laboratory benches without occupying excessive space, supporting organized and efficient laboratory work. The unit is supplied with necessary leads, load accessories, and instructional guidance to facilitate installation, experimentation, and routine operation.
